Application filed November 17, 1923.. Serial No. 675,386.

My invention relates to an improvement in oil tanks.

The object is to provide a tank preferably of sheet-metal, as distinguished from glass, for containing the oil used for supplying burners, such as are commonly employed with incubators and brooders. This present invention is considered a decided improvement onthe glass container, and consists in the main in a. metal tank having an outlet in the bottom controlled by a valve, in connection with a float chamber and float, which latter rests upon the surface of the Oil and automatically controls the valve with respect to the oil level.

This invention further consists in means for regulating the'flow of oil from the upper to the lower chamber of the tank.

The accompanying drawing is a vertical sectional view through the oil-tank and.float-- chamber. v

The numeral '1 represents the oil tank preferably of sheet-metal; 2 is the float chamber of similar material, the two being fitted together like any sheet-metal pipe, and one preferably having an open slot a to receive pin 6 on the other. i

The numeral 3 indicates a sheet-metal float which rests upon the oil in the floatchamber 2, and which is always'held at a certain elevation above the bottom (even when the oil is low) by rests 0. A-pertorated valve-stem guide A depends from the bottom of the oil tank 1. at the center, and

this is provided with oil inlets at above the bottom of the oil tank and oil outlets e below the bottom. A needle-valve 7 projects downward into the center of a reticulated cone 9 in the middle of thefloat, through the lower end of the perforated valve-stem guide in position to engage the valve-seat h, or in other words the oil level controls the position of the needle-valve f and the size of the opening between it and its'seat k.

A strainer ring 5 surrounds the upper end of the perforated v'alve stem'guide 4, through which theoil passes andis strained on its passage to the inlets d and the outlets e of the valve stem guide 4. This strainer 5 is covered by aremovable cap 2' held on by friction.

A shut-off valve 6 is screwed into the upfoperator, as shown in Fig. 1.

per end of the valve-stem guide 4 for coutrolling the movement of oil permittingit to enter the inlets d, and the stem of this shut-off valve extends well up toward the top of the tank within easy reach of the V A cover j is removably placed on the top of the tank. A lock screw wheel 7 is mounted on the threaded stem is, which supports the float chamher, and a look-screw lever 8 is adapted to be removably inserted in any one of the several sockets Z in the lock-screw wheel 7 for turning the latter.

To raise and lower the oil tank and float chamber, the threaded stem is turned in the base m whereupon the lock-screw wheel is extends horizontally from the base m to a burner (not shown).

' At some intermediate point in the pipe n, there is a fitting t having a valve-seat u, and this is controlled by a valve 0) and a stem w extending up to a point within easy reach of the operator. A pointer w connected with the valve operates in conjunction with a dial "y for indicating to the operator the exact position of valve-seat u with relation to its valve '0.

Thus is provided a simple all-metal com- I bination of tank along with the required valves and connections and the adjustments necessary to regulate the oil supply and F1 bring it within the control of the attendant.

I claim:

. 1. A device of the character described ineluding a float. chamber, a float having an op eningjsubstantially therethrough, and an inverted reticulated cone in said opening and having its-upper peripheral edge secured to the edges of the outer end of said said float chamber having a pin secured thereto, and the oil tank having a slot therein to receive the pin for holdingthe parts together.

In testimony whereof I'aflix mysignature.
